To a/ZZ whom t may concern:

Be it known that I, JOHN SWRIGHT, a citizen of the United States,residing at Duxbury,

'in the county of Plymouth and State of Massachusetts, have invented newand useful Irnproveinents in Fountain-Pens, of which the following is aspecification.

The object of this invention is to produce afountain-pen which will notleak when carried in the pocket with the pen pointing downward, and,further, to produce a pen which can be filled by means of a devicelocatedin the interior of the handle thereof; and, further, it is theobject of this invention to produce a fountain-pen which shall bepractical and durable in' construction and 'the' size of which shall notexceed that of the fountainpens in ordinary use. v

The -invention consists in the combination and arrangement of parts setforth in the followingspecication, and particularly pointed p ont in theclaims thereo Referring to the drawings, Figure 1 is a centrallongitudinal section of myimproved foun` tain-pen. Fig. 2 is an enlargedcentral longitudinal section of a portion of the pen handle or staffnear the end at which the pen is attached and also of the piston andpistonrod, by means ofl which said pen-handle is lled with ink. Fig. 3is an enlarged centralv longitudinal section of a portion of the pen 4handle or stai and the parts contained therein at the opposite end tothat at which the pen is attached. Fig. 4is an enlarged transversesection taken on line 44, Fig. 1, looking toward the penholder.Fig.isasimilarsection taken on line 5 5, Fig. 2,1ooking in the samedirection. Fig. 6 is a section on line 6 6, Fig. 1. Fig. 7 is anenlarged central longitudinal section of the valve-rod head and aportion of the valve-rod and piston-rod., Fig. 8 is a section on line 8S, Figp, looking toward the penholder. Fig. 9 is an end elevation of thecap 22 with the rotator therein. Fig. 10 is an end elevation of theplate 33 upon the valverod head. Fig. 11 is a sectional View of amodified form of penholder.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 10 is the handle of the pen, consisting of a hollowcylinderhavinga holder 11 for the pen at one end, which also constitutesa feeder for the pen 12. The holder 11 is cylindricalfor a portion ofits length, as at 13, and vis groovedat 14 to receive the shank of apen, which is held in said groove between the cylindrical portion 13 ofthe holder and the inner periphery of the hollow cylindrical handlel0'.v The holder 11 is provided with a feed-point 15,which extendsoutwardly therefrom to a point near the nibsof the pen, against theinner face of which said feedpointbears. from the inner chamber 17 ofthe pen-handle 10 to the nibs ofthe pen. At the opposite A passage 16conducts the ink v end of the pen-handle 10 to that at which the 1 andhaving an enlarged portion 20' thereon,

whichfornis a shoulder to bear against the end of the..penhandle 10. Theplug 18 is screw-threaded at 21 to receive a cap 22. Said caphas areduced cylindrical portion 23 of a diameter to receive the pen-covery24. When the pen is not in use, the cover 24 is applied to the end ofthe handle 10, as shown in Fig. l, and when in use the pen-cover isplaced upon the cap 22, as shown in dotted lines, Fig. l1. i

In order to till the chamber'17 with ink and also to provide a means forpreventing the ink from leaking out of said chamber when the pen is notin use and is placed in anv inverted position-as,for instance,in thepocket with the pen pointing downwardly-'J 'provide in the chamber 17apiston 25, having a.

therewith. The piston 25 is packed with a ring of cork 27 and has-twoopenings or'ports through.- The tubular piston-rod 26 has a bearingconsisting of a cork tube or sleeve 28, fast in the interior of a holedrilled in the center of the plug 18. A rotary valve 29, havtubularpiston-rod 26 fast thereto orintegral ing two parts 30 therein, bearsagainst the*l outer end face of the piston 25andis fast to a rotaryvalve-rod 31. The valve-rod 31 fits the interior-of the tubularpiston-rod 26 and is provided with a cylindrical head 32, by means ofwhich it may be rotated, together with the valve 29. The head 32 has aplate 33 riveted thereto, and a pin 34, fast to said head 32,` projectsinto a slot 35, formed in a ICO 37 therein extendinglongitudinallytheref ange 36, integral with the tubular pistonrod 26, said slotextending through an angle of about ninety degrees. W'hen the parts areinthe relative positions indicated in the drawings, the pin 34 is at theright-hand end of the slot and the ports 37 in the piston 25 are thenclosed. Upon rotating the head 32 to the left or in the direction of thearrow, Fig. 8, the valve 29 will be rotated by means of the rod 3l untilthe ports 30 come inv line with the piston-ports 37, and the pin 34 willmove around in the slot 35 until it comes to the upper end of said slot.When the ports in the piston and in the valve are thus brought intoalinement, it is evident that the ink will ilow out of the chamber 17 tothe pen 12 or 4that ink may be pumped into said chamber,

as hereinafter described.

When the cap 22 is removed from the handle 10 by unscrewing the same,the head 32 may be rotated directly by the fingers to open and close thepiston-ports, as hereinbefore described; but to avoid the necessity ofremoving said cap, which would be inconvenient, I provide avalve-rotator 3S, consisting of a stem 39, which may be rotated in abearing in the cap 22 by means of a flange 41, fastto said stem andhaving a slot 42 across the facethereof, by means of which said rotatormay be rotated by inserting the thumbnail therein and turning it.

The stem 39 has a head 43 thereon, which is square in cross-section andtapers longitudinally to fit a square hole 44 in the plate '33, so thatas the flange 41 is rotated the plate 33, head 32, valve-rod 3l, andvalve 29 will rotate with it, and according to the direction in whichsaid collar is rotated the pistonports 37 will be opened or closed, ashereinbefore described.

It will be seen 'that when the pen is in the pocket in an invertedposition, with the cap 22 attached to the plug 18, the valve-rod head 32cannot be accidentally rotated, thus rotating the valve 29, openingthepiston-ports 37, and allowing the ink to flow out. The periphery ofthe flange 41 being surrounded by the reduced portion 23 of the cap 22,said liange'cannot be accidentally rotated by rubbing against theclothing.

In order to provide for the escape of air from the chamber` 17 when thepiston is being raised in the operation of illing,I unscrew the plug 18by 4means of the enlarged portion 20 until said enlarged portion 2O isdrawn away from the end of the pen-handle 10, thus allowing the air toescape around the screw-thread 19, which is made sufficient-ly loose forthe purpose, and between the enlarged portion 2O and the end of saidpen-handle. Prior to returning the pistonto the osition shown in Fig. 1after the ink has owed into the chamber 17 ,as hereinafter described,the plug 18 is screwed tightly into the penhandle 10, with the enlargedportion thereof bearing against the end of said handle and forming atight joint, which prevents the ink from flowing out of the chamber 17at that point. p

The operation of the device is as follows: To till the chamber 17 withink, assuming the parts to be in the position shown'in Fig. 1, the cap22 and the pen-cover 24 are removed from the handle 10, the plug 18 isunscrewed one or two turns, the pen and holder are next inserted in theink to about the depth of lthe line 6 6, Fig. 1, and the piston 25 andvalve 29 drawn lengthwise of the handle 10 away from the pen 12 by meansof the valve-rod head 32, thus creating a vacuum in the chamber 17, intowhich the ink from the ink-well flows, filling said chamber 17 as thevalve and piston are drawn back therein until the piston abuts againstthe plug 18. Said plug 18 is then screwed into the handle 10 until theshoulderlformed by the enlarged portion 20 is brought to bear firmlyagainstthe end of the handle 10, forming a tight joint therewith. Thevalve-rod head `32 is then turned to theleft, thus rotating thevalve-rod and valve'until the valve-ports 30 come in line with thepiston-ports 37. remain stationary on account of the friction of thecork ring 27 and cork sleeve 28 until the pin 34 arrives at the upperend of `the slot 35, Fig. 8, when the piston and valve ports will beinalinement, and any further rotation of the head 32 to the left willcause both valve and piston to rotate together.v The piston and valveare now pushed forward slowly, and the ports 30 and 37 being inalinement the ink in the chamber 17 will iiow through said ports fromthe front to the rear side thereof until said piston and valve have beenpushed forward to the front end of the chamber 17. The penis nextremoved from the ink-well and wiped. If it is now desired to write withthe pen, the cap 22 is screwed upon the screw-threaded 'portion u21 ofthe holder and the pencover 24 is placed upon the reduced cylindrical`portion 23 of said cap, as shown in dotted lines, Fig. 1, and the penis in readiness for use. If it is desired to place the pen inthe pocketwithout leaking when the pen is inverted, the head 32 is turned to theright Afor not less thana quarter of one rotation, bringing therespective parts into the relative positions shown in the drawings andclosing the piston-ports 37 by turning the valve-ports 30 out ofalinement therewith.

1n Fig. 11 the handle 45 is `beveled to receive a pen-cover 46, alsobeveled uponthe inside to fit thereon, and the cap '47 is also beveledto receive said cover.
